Abstract
Background: Terpolymer have versatile applications in adhesives, electroluminescent devices,
packaging, coating materials, ion exchanger and hardener for epoxy resin.
Objective: In the present investigation, our main aim was to synthesize terpolymer using 8-
hydroxyquinoline-5-sulphonic acid, anthranilic acid and formaldehyde (8-HQ-5-SAAF) via the polycondensation
method and to evaluate thermal properties of terpolymer.
Materials and Methods: 8-Hydroxyquinoline-5-sulphonic acid, anthranilic acid and formaldehyde
were used for synthesis. Terpolymer was obtained by employing the polycondensation method.
Results: TGA analysis shows that the synthesized terpolymer resin was thermally stable. The activation
energy calculated by Freeman-Carroll and Sharp-Wentworth methods has been found to be in
good agreement with each other. The low value of frequency factor and negative entropy value indicate
that the thermal decomposition would be a slow reaction.
Conclusion: The thermal energy of activation calculated by using Sharp-Wentworth and Freeman-
Carroll methods has been found to be nearly identical. The terpolymer 8-HQ-5-SAAF starts degradation
at high temperature, showing that this polymer resin is thermally stable.
